UnitedStates PROTECTIVE WORKING GLOVE Egbert Michael-Lohs, Traunring 5, Trauureut, uber Traunstein, Germany Filed Nov. 26, 1957, Ser. No. 699,086 7 Claims priority, application Germany Nov. 27, 1956 8 Claims. (Cl. 66-174) The invention relates to a protective working glove intended especially for the metal-working industry, and in particular for grasping sharp-edged sheet-metal. For example, press operators are often exposed to the danger of considerably injuring the palm of the hand when removing sheet metal from punching machines. Hitherto, coarse leather gloves have been used for protective purposes, but these gloves have the disadvantage that, even after a short period of use, they may become unsuitable for further use in consequence of a single cut caused by sharp-edged sheet metal. These coarse leather gloves also have the defect that they make it diflicult for the operator to feel the sheet metal and this hinders rapid and frictionless work.

The present invention provides a protective working glove consisting of a tube-like knitted glove which leaves the ends of the fingers and thumbs free and is knitted from spun synthetic fibre yarn and monofilament synthetic yarn in such manner that the monofilament yarn is positioned substantially on the outer surface of the glove, whereas the spun yarn is substantially on the inner side and constitutes a soft internal surface of the glove, since this yarn comprises a plurality of fine, smooth synthetic fibres. With the aid of this protective glove, the endangered portions of the hand are enclosed satisfactorily in a comfortable manner. The inner surface consisting of synthetic spun yarn (for example polyamide yarn) protects the hand against friction elfects, whereas the extremely tough monofilament synthetic yarn (manu factured from a polyamide) on the outer side of the glove offers an extremely effective form of protection against cuts. Due to the fact that the end portions of the fingers and thumbs remain free, quicker and firmer grasping of the sheet metal by the operator is ensured, and this is essential for the speedy progress of the work in hand.

Further features of this protective working glove are described in detail hereinafter with reference to an embodiment illustrated in the accompanying drawings, wherein Fig. l is a view of a protective glove;

Fig. 2 is a view of the protective glove of Fig. 1 positioned on the hand; and

Figs. 3 and 4 show the outer and inner sides, respec tively of the knitted mesh of the protective glove.

As shown in Figs. 1 and 2, the protective working glove is knitted in the form of a roughly tubular portion 1 with a sleeve-like portion 2 to accommodate the thumb. As will be apparent from Fig. 2, this protective working glove is so designed that the ends 3 of the fingers and also the end 4 of the thumb remain free, so that rapid and secure grasping of sheet-metal or the like is made possible. Injury by sharp sheet-metal edges or the like is, however, effectively prevented by the glove. The glove is manufactured from a combination of synthetic'spun yarn (spun from synthetic fibres) and synthetic monofilament yarn. The spun yarn and the monofilament yarn are knitted to form the protective glove in such p 2,942,442 Patented June 28; 1960 manner that, as shown in Figs. 3 and 4, the wire mesh 5 is positioned substantially on the outside of the glove, whereas the spun, yarn indicated at 6 is positioned substantially on the inside of the glove, thus forming a' soft, smooth internal surface which prevents friction. The hardly visible portions -5 of, the monofilament yarn on the inside of the glove are so deeply embeddedvin the knitted fabric that they do not come into contact with the hand. On theother hand, it is apparent from Fig. 3 that the synthetic monofilament yarn 5 is placed sub-. stantially on the outside of the glove, so that it efiectively protects the spun yarn 6 and also the hand against injury by cutting.

The new protective working glove is manufactured in known manner on twin-cylinder circular knitting machines. With the aid of a special arrangement-of the thread guide, it is ensured that one of the materials, i.e., the spun yarn, is always on the inside,- and the other material (synthetic wire) is always on the outside.

Advantageously, theglove tube 1 is, as shown in the drawing, made symmetrical about the cent-re line a a, so that the thumb portion 2 is knitted on exactly in the centre of the tube 1. This special symmetric design has the advantage that the glove can be pulled over the hand from either side and that, furthermore, the glove can be worn both on the right and on the left hand. Thus there are four different ways of using the glove, so that the useful life of the glove is quadrupled as compared with conventionally designed protective gloves which can only be worn on one hand and in one position. The glove tube 1 may be provided at bothends with an elastic knitted collar 70f soft synthetic spun yarn, as shown in Figs. 1 and 2. The fingers and the wrist are enclosed in a pleasant and soft manner by these knitted collars.
